Description

Technical Field

[0001] This application relates to the field of pathological slide baking technology, and more particularly to a microwave-heated pathological slide baking device. Background Technology

[0002] A pathology slide drying machine is an important piece of equipment used for preparing pathological slides. It is widely used in hospital pathological diagnosis, pathology laboratories, and other histological research. Its main function is to shape and dry the slides to ensure they remain in good condition for subsequent staining and observation.

[0003] In conventional pathological slide preparation, the flatbed constant-temperature pathological slide warmer is the most commonly used equipment. After setting the warming temperature, it can heat the pathological slides in contact. However, it has disadvantages such as long heating time and easy damage to the pathological slides: because contact heating is inefficient and can lead to uneven heating of different parts of the pathological slide, the heating temperature needs to be lowered, resulting in a longer heating time; for some fatty tissues or tissues with high water content (such as brain tissue), the slides are prone to shrinkage during heating, and because the pathological slides need to be in contact with the warmer, it is easy to cause the slides to tear or deform, resulting in incomplete slides, which requires rework, increases workload, and reduces work efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a microwave-heated pathological slide baking device, which aims to solve the problems of easy damage to slides and low efficiency of existing pathological slide baking devices.

[0005] The technical solution adopted by this application to solve the technical problem is as follows: a microwave-heated pathological slide baking device, comprising: an air flotation plate, wherein the air flotation plate has a suspension zone, and the suspension zone is used to support the pathological slide; A limiting device is connected to the air flotation plate and is used to confine the pathological slide within the suspension zone. A microwave heating module is provided, which is positioned toward the suspension zone, and is used to heat the pathological slides within the suspension zone.

[0006] Furthermore, the air flotation plate includes: a plate body, the plate body being horizontally arranged, and the suspension zone being disposed on the plate body; A plurality of air vents are provided on the plate and located within the suspension zone; An air pump is connected to several air outlets and supplies high-pressure air to the air outlets.

[0007] Furthermore, the limiting device includes an annular baffle, which is disposed on the air flotation plate, and the suspension zone is formed between the baffle and the air flotation plate.

[0008] Furthermore, the limiting device also includes a laser grating, which is horizontally arranged and is used to generate an obstruction signal when the pathological slide is moved out of the suspension area.

[0009] Furthermore, the limiting device also includes a height control module, wherein the air pump and the laser grating are respectively connected to the height control module, and the height control module adjusts the air pump to a first power by receiving the occlusion signal generated by the laser grating, wherein the first power is lower than the preset operating power of the air pump.

[0010] Furthermore, the pathological slide baking equipment also includes a thermochromic film, which is disposed in the suspension zone and changes to a predetermined color based on the temperature of the pathological slide.

[0011] Furthermore, the color-changing temperature of the thermochromic film is 65°C.

[0012] Furthermore, the size of the thermochromic membrane is larger than that of the pathological section.

[0013] Furthermore, the temperature control module also includes a color detection switch, which is positioned towards the suspension area and is used to detect the preset color and then send a shutdown signal to the microwave heating module.

[0014] Furthermore, the pathological section baking equipment also includes: a frame; The metal casing is mounted on the frame, and the microwave heating module, the limiting device, and the air flotation plate are all disposed inside the metal casing.

[0015] Compared with the prior art, this utility model heats pathological slides using a microwave heating module, resulting in higher heating efficiency and more uniform heating. Furthermore, the pathological slides are supported by airflow through an air flotation plate, which prevents direct contact between the pathological slides and the air flotation plate. This also makes it less likely for the slides to tear or deform when heated, especially when heating adipose tissue or tissues with high water content (such as brain tissue).

[0022] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0023] This utility model provides, for example Figures 1 to 5 The microwave-heated pathology slide baking device shown is designed to address the problems of existing pathology slide baking devices that easily damage slides and are inefficient.

[0024] This microwave-heated pathological slide baking device 700 mainly includes: an air-floating plate 100, a limiting device 200, and a microwave heating module 300. The air-floating plate 100 has a suspension zone 112, which is used to support the pathological slide 700. Specifically, the air-floating plate 100 can use the buoyancy generated by the flowing airflow to overcome gravity and suspend the object. Its core principle is to form an air film between two contacting objects, forming a stable "air cushion" under the object, thereby lifting and suspending the object and reducing friction between the two. This ensures that there is an air film between the pathological slide 700 and the air-floating plate 100, reducing the friction between them. When heating some fatty tissue or tissues with high water content (such as brain tissue), it is less likely to cause the slide to tear or deform.

[0025] The limiting device 200 is connected to the air flotation plate 100. The limiting device 200 is used to confine the pathological slide 700 within the suspension zone 112. The microwave heating module 300 is positioned facing the suspension zone 112 and is used to heat the pathological slide 700 within the suspension zone 112. In actual use, because the friction between the pathological slide 700 and the air flotation plate 100 is extremely small, it is easily affected by various factors, causing it to slide on the air flotation plate 100. Therefore, the limiting device 200 is needed to confine it within the suspension zone 112, allowing it to be continuously irradiated and heated by the microwave heating module 300. It should be noted that the microwaves emitted by the microwave heating module 300 have a certain impact on the human body, and it is necessary to set up a corresponding shielding structure. This shielding structure is already very mature (refer to the structure of a microwave oven), so it will not be described in detail further.

[0026] In conventional pathological slide preparation, the flatbed constant-temperature pathological slide warmer is the most commonly used equipment. After setting the warming temperature, it can heat the pathological slides 700 in contact. However, it has disadvantages such as long heating time and easy damage to the pathological slides 700: due to the low efficiency of contact heating, it can lead to uneven heating of different parts of the pathological slides 700, which requires lowering the heating temperature, resulting in a long heating time; for some fatty tissues or tissues with high water content (such as brain tissue) slides, they are prone to shrinkage during heating. Since the pathological slides 700 need to be in contact with the warmer, it is easy to cause the slides to tear or deform, resulting in incomplete slides, which requires rework, increases workload, and reduces work efficiency.

[0027] This invention uses a microwave heating module 300 to heat the pathological slide 700, resulting in higher heating efficiency and more uniform heating. Furthermore, the air flotation plate 100 supports the pathological slide 700 with airflow, thus preventing direct contact between the pathological slide 700 and the air flotation plate 100. This also makes it less likely for the slide to tear or deform when heating some fatty tissue or tissues with high water content (such as brain tissue).

[0028] In some embodiments, such as Figures 1 to 3 As shown, the air flotation plate 100 includes: a plate body 110, which is horizontally arranged, and a suspension zone 112 is arranged on the plate body 110; A number of air vents 111 are provided on the plate 110 and located in the suspension zone 112; Air pump 120 is connected to several air outlets 111 and inputs high-pressure air into the air outlets 111.

[0029] Specifically, the plate 110 is a metal structure that can reflect microwaves. It can reflect the microwaves emitted by the microwave heating module 300, preventing the microwaves from irradiating other objects. At the same time, the partially reflected microwaves can be used to irradiate the pathological slide 700 again, improving the utilization rate of microwaves.

[0030] In some embodiments, such as Figures 1 to 3 As shown, the limiting device 200 includes an annular baffle 210, which is disposed on the air flotation plate 100, and a suspension zone 112 is formed between the baffle 210 and the air flotation plate 100.

[0031] In practical use, due to the extremely low friction between the pathological slide 700 and the air flotation plate 100, it is easily affected by various factors, causing it to slide on the air flotation plate 100. The annular baffle 210 confines the pathological slide 700 within the suspension zone 112, thereby limiting its horizontal movement and ensuring that the pathological slide 700 can be continuously irradiated and heated by the microwave heating module 300. Preferably, the baffle 210 is also made of a microwave-reflective metal material.

[0032] In some embodiments, such as Figures 1 to 3 As shown, the limiting device 200 also includes a laser grating 220, which is horizontally arranged and is used to generate an obstruction signal when the pathological slice 700 is removed from the suspension area 112.

[0033] Specifically, the laser grating 220 is formed by multiple through-beam photoelectric sensors arranged at intervals along the same direction, such as... Figure 1 and Figure 2 As shown, each pair of cooperating through-beam photoelectric sensors are respectively positioned at opposite ends of the suspension zone 112, and the laser coverage strip 210 of each pair of cooperating through-beam photoelectric sensors faces away from the opening of the air flotation plate 100. This ensures that when the pathological slide 700 moves out of or protrudes from the suspension zone 112, it partially blocks the laser beam, allowing it to be detected by the corresponding through-beam photoelectric sensor. During baking, the pathological slide 700 is parallel to the plate 110. To improve accuracy, the laser spacing between adjacent through-beam photoelectric sensors is less than the minimum width of the pathological slide 700 on the horizontal plane.

[0034] In some embodiments, such as Figure 4 As shown, the limiting device 200 also includes a height control module 230. The air pump 120 and the laser grating 220 are respectively connected to the height control module 230. The height control module 230 adjusts the power of the air pump 120 to a first power by receiving the occlusion signal generated by the laser grating 220. The first power is lower than the preset working power of the air pump 120.

[0035] In actual use, when the pathological slide 700 moves out of or protrudes from the suspension area 112, the blocked through-beam photoelectric sensor sends a blocking signal to the height control module 230, thereby reducing the power of the air pump 120 to lower the height of the pathological slide 700 and prevent it from leaving the suspension area 112. It should be noted that the initial power of the air pump 120 should be set appropriately to prevent the pathological slide 700 from flying directly out of the suspension area 112, which could cause the laser grating 220 to misjudge that the pathological slide 700 is still within the suspension area 112. The height control module 230 is only used to fine-tune the power of the air pump 120 to accommodate slight weight differences between different pathological slides 700.

[0036] In some embodiments, such as Figure 5 As shown, the pathology slide 700 baking device also includes a thermochromic film 500, which is disposed in the suspension zone 112 and used to cover the pathology slide 700. After reaching the color-changing temperature, the film changes to a preset color.

[0037] Specifically, microwaves mainly act on water molecules, and their heating effect on the dry thermochromic film 500 is generally limited. Therefore, the thermochromic film 500 can reflect the temperature of the pathological slide 700 to a certain extent.

[0038] In some embodiments, the color-changing temperature of the thermochromic film 500 is 65°C. This is suitable for the preparation requirements of most pathological slides 700.

[0039] In some embodiments, such as Figure 5 As shown, the thermochromic membrane 500 is larger than the pathological slide 700, allowing for better temperature feedback.

[0040] In some embodiments, such as Figure 4 As shown, the temperature control module also includes a color detection switch 400, which is positioned toward the suspension area 112. The color detection switch 400 is used to detect a preset color and then send a shutdown signal to the microwave heating module 300.

[0041] Specifically, when the color detection switch 400 detects the preset color, it indicates that the temperature of the pathological slide 700 has reached the required level and heating needs to be stopped. At this time, the color detection switch 400 can turn off the microwave heating module 300, thereby automatically stopping the heating.

[0042] In some embodiments, such as Figures 1 to 3 As shown, the pathology slide baking apparatus 700 also includes: frame 610; The metal casing 620 is mounted on the frame 610, and the microwave heating module 300, the limiting device 200, and the air flotation plate 100 are all mounted inside the metal casing 620.

[0043] Specifically, the metal casing 620 can be designed with reference to the structure of a microwave oven to prevent microwave leakage.

[0044] In summary, a microwave-heated pathological slide baking device is provided, including an air-float plate, a limiting device, and a microwave heating module. The air-float plate has a suspension zone for supporting the pathological slides. The limiting device is connected to the air-float plate and is used to confine the pathological slides within the suspension zone. The microwave heating module is positioned towards the suspension zone and is used to heat the pathological slides within the suspension zone. This invention heats the pathological slides using a microwave heating module, resulting in higher heating efficiency and more uniform heating. Furthermore, the air-float plate supports the pathological slides with airflow, thus preventing direct contact between the pathological slides and the air-float plate. This also reduces the likelihood of tearing or deformation of slides containing fatty tissue or tissues with high water content (such as brain tissue) during heating.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
